[R] Equivalent of log file in R?

[Spencer Graves]

       If I read the help file correctly, another alternative is as 
follows:


             sink(file="my_R_log.txt", split=TRUE)


       "split = logical: if TRUE, output will be sent to the new sink 
and to the current output stream"


       Hope this helps,
       Spencer
